Description

Technical Field

[0001] The invention relates to the technical field of fish breeding pond sterilization devices, in particular to an ultraviolet sterilization device for fish breeding ponds. Background Art

[0002] Ultraviolet disinfection is a physical sterilization method. Recirculating aquaculture is a highly efficient aquaculture method characterized by the recycling of aquaculture water after purification. It has the advantages of controllable conditions, water saving and environmental protection. At present, ultraviolet sterilization in recirculating aquaculture systems mostly adopts the form of fixed sterilization devices. Usually, the ultraviolet disinfection device is installed in a specific water channel position to allow the circulating water to flow continuously through the device. The radiation effect of ultraviolet rays is used to destroy the genetic material of harmful microorganisms such as bacteria, viruses, algae, etc. in the water body, thereby achieving the effect of sterilization and algae removal and purifying water quality.

[0003] However, this traditional fixed setting method has obvious limitations. In fish breeding ponds, the bottom environment has its own particularity. Since organic matter such as feed residues and fish excrement are easily deposited here, a hotbed for the growth of microorganisms is formed. The water flow at the bottom of the pond is relatively slow. Some pathogenic organisms, such as bacteria and parasite eggs, can attach and multiply in the gaps, corners and sediment surfaces at the bottom of the pond. The fixed ultraviolet disinfection device mainly treats the water flowing through it, and it is difficult to have a direct and effective sterilization effect on the gathering places of pathogenic organisms at the bottom of the pond. This leads to the continued existence of hidden dangers of diseases at the bottom of the pond, which may periodically release harmful organisms into the entire breeding water body, causing the outbreak of fish diseases, affecting the growth and development of fish, reducing the survival rate of breeding, increasing the cost of drug use, and even destroying the balance of the entire breeding ecosystem, which seriously restricts the efficient and sustainable operation of the recirculating aquaculture system. Summary of the invention
